Using AdMob and Firebase Analytics, I'm trying to let users change their AdMob consent type in App's Settings by letting them turn a switch on/off for personalized ads (If users turn the switch "On", they would get personalized ads and if they turn it "Off", they would get non-personalized ads). I wrote a code, but it gives me errors and it also loops. What is the correct way/code to do so?
Here is what I am currently doing: 1- Added a toggle switch item in Settings.bundle>Root.plist with identifier "GooglePersonalizedAds" to let user turn the switch on/off in the app's setting
2- Added "FIREBASE_ANALYTICS_COLLECTION_ENABLED" and "GOOGLE_ANALYTICS_DEFAULT_ALLOW_AD_PERSONALIZATION_SIGNALS" as "boolean" properties in my app's "info.plist" and set their value to "NO".
3- To initialize FireBase, In AppDelegate I added:
FirebaseConfiguration.shared.setLoggerLevel(.min)
FirebaseApp.configure()
4- In the viewDidLoad() of the ViewController.swift, I added:
registerSettingsBundle()
NotificationCenter.default.addObserver(self, selector: #selector(ViewController.defaultsChanged), name: UserDefaults.didChangeNotification, object: nil)
defaultsChanged()
5- In ViewController.swift, I added:
@objc func defaultsChanged(){
let userDefault = UserDefaults.standard //Fetch value from Settings.bundle
if !purchasedUser {
if userDefault.bool(forKey: "GooglePersonalizedAds") {
print("GooglePersonalizedAds changed to: \(userDefault.bool(forKey: "GooglePersonalizedAds"))")
Analytics.setUserProperty("true", forName: AnalyticsUserPropertyAllowAdPersonalizationSignals)
self.view.backgroundColor = UIColor.red // To Test the implementation of personalized/non-personalized ads switch in App's settings
Analytics.setAnalyticsCollectionEnabled(true)
PACConsentInformation.sharedInstance.consentStatus = .personalized
let request = GADRequest()
let extras = GADExtras()
extras.additionalParameters = ["npa": "0"]
request.testDevices = [testDeviceString]
request.register(extras)
}
else if !userDefault.bool(forKey: "GooglePersonalizedAds") {
print("GooglePersonalizedAds changed to: \(userDefault.bool(forKey: "GooglePersonalizedAds"))")
Analytics.setUserProperty("false", forName: AnalyticsUserPropertyAllowAdPersonalizationSignals)
self.view.backgroundColor = UIColor.green // To Test the implementation of personalized/non-personalized ads switch in App's settings
Analytics.setAnalyticsCollectionEnabled(false)
PACConsentInformation.sharedInstance.consentStatus = .nonPersonalized
let request = DFPRequest()
let extras = GADExtras()
extras.additionalParameters = ["npa": "1"]
request.testDevices = [testDeviceString]
request.register(extras)
}
} else if purchasedUser {
print("GooglePersonalizedAds changed to: \(userDefault.bool(forKey: "GooglePersonalizedAds"))")
Analytics.setUserProperty("false", forName: AnalyticsUserPropertyAllowAdPersonalizationSignals)
self.view.backgroundColor = UIColor.green
Analytics.setAnalyticsCollectionEnabled(false)PACConsentInformation.sharedInstance.consentStatus = .nonPersonalized
}
registerSettingsBundle()
}
func registerSettingsBundle(){
let appDefaults = [String:AnyObject]()
UserDefaults.standard.register(defaults: appDefaults)
}
When I run the app, I get many "GooglePersonalizedAds changed to: false" printed in the console and finally the app crashes with an error. One error that I got after crash was: "Thread 1: EXC_BAD_ACCESS (code=2, address=0x7ffeeb86ffd8)" error for "NSUserDefaults.standardUserDefaults setObject:personalizedAdStatus forKey:PACUserDefaultsRootKey]"
I think the errors come from: "Analytics.setAnalyticsCollectionEnabled(false)PACConsentInformation.sharedInstance.consentStatus = .nonPersonalized" or "PACConsentInformation.sharedInstance.consentStatus = .personalized" which change the UserDefaults, and therefore call the observer and defaultsChanged() and so, create a loop.
How may I set the Analytics.setAnalyticsCollectionEnabled(false)PACConsentInformation.sharedInstance.consentStatus to .personalized or .nonPersonalized by using a switch (identifier: GooglePersonalizedAds in App's setting, as tries in my question?
